Hi @Hillary_Smith! I noticed you’re using the 2017.10 release of QIIME 2. At this time we’re only able to provide support for the latest release, which is currently 2017.12. Can you please try installing that release?
I tried rerunning the command with your data set in the 2017.12 release and I receive the same error message. It looks like none of the 447 feature IDs in your feature table (no-misses-filtered-table-f270-r240.qza) are contained in the taxonomy annotations (sample-taxonomy-silva-99-hits-un-extracted.qza). Is it possible those files got mixed up at some point? You can take a look at the data provenance for those files using https://view.qiime2.org, that may help you with tracking this down.
Note: The error message being raised by qiime taxa barplot isn’t very helpful with determining what went wrong. We have an open issue to improve the error message in a future release. We’ll follow up here when that’s available!
